The Perth woman died last month just short of her 30th birthday, leaving behind her 10-month-old baby Ivy and her partner Tommy Corrigan.

Liz was first diagnosed when she was just 23 years old but was able to beat the deadly disease.

Months after giving birth to her first child in January, she began experiencing small abdominal pains but initially put them down to being a new mum.

It was then that doctors diagnosed stage-four metastatic melanoma.

The cancer had taken hold in her brain and just one day after speaking to 7 News about her incredible battle back in August, Liz was rushed to hospital, paralysed down one side of her body and unable to talk.

A few weeks before her death, doctors deemed any treatment was futile.

The 29-year-old had been very vocal about her battle over the years, raising awareness about the importance of early detection.
